Set in an alternate America, Watchmen follows costumed hero Rorschach, who is living a vigilante lifestyle because most masked heroes have retired or been outlawed. While investigating a murder, Rorschach learns that a former masked-hero colleague has been killed, prompting him to begin investigating a possible conspiracy.

Haley will play Walter Kovacs, aka Rorschach, who ignores the ban on costumed vigilantes.

Crudup will play Dr. Manhattan, a superpowered being with godlike powers and temperament.

Akerman will play Laurie Juspeczyk/the Silk Spectre, who is involved with Dr. Manhattan — but that relationship begins to fall apart as he becomes more disconnected from humanity.

Goode will play Adrian Veidt/Ozymandias, a costumed adventurer who retired voluntarily, disclosed his identity and built a large fortune. He hatches a plot to avert a global catastrophe he believes will be caused by Dr. Manhattan.

Wilson will play the Nite-Owl, a crime-figher who uses technical wizardry and has an owl-shaped flying vehicle.

Morgan will play the Comedian, a cigar-chomping, gun-toting vigilante-turned-paramilitary agent.
